The collapse of the presolar cloud gave rise to a global homogenization of material available to form the Sun and planets. In the resulting, presumably homogeneous solar system, the nuclides are present in proportions referred to as their cosmic abundances. Here we report molybdenum isotopic compositions of bulk samples and leachate fractions of the primitive meteorites Orgueil and Allende. Two complementary nucleosynthetic components are revealed in Orgueil. One (Mo-m) is enriched in s-processdoi:10.1086/340580 fatcat:mmx7aecfhfgy3ingg5qv4rsnfm
